Description

Turning-over tank filter with sealing cap

The utility model is a kind of turning-over tank type filter that adds seal cover, belongs to liquid-solid separating centrifuge tool filter plant technical field.

In the production process of many industries, generally use the vacuum suction filter bucket (groove) of intermittently operated to filter at present, the disposable a large amount of blowings of reaction pot filter and the needs of washing to satisfy.The filter of this equipment is unloaded operation side by side and is relied on artificial.When large-scale suction strainer groove was slagged tap, the workman must wear boots and enter the interior shovel filter of groove also; Small-sized suction strainer bucket then needs the workman to bend over to operate and shovels out filter also; Also method such as useful Pig draw off filter and.This class methods labour intensity height, time-consuming, filter and in easily sneak into rubbish and influence quality, filter also loss is big, workshop condition is seriously polluted, it is frequent that the mounting or dismounting of filter cloth are cleaned, cracky, operating cost is big.The rotary vacuum filter though existing now operation turns over comparatively easily, the frame of its filter disc is too low, can not adapt to the needs that once advance the slurry operation in a large number, more can not install seal cover additional, thereby its scope of application has certain limitation.

The purpose of this utility model, be to overcome the shortcoming of above-mentioned two kinds of existing filter plants, comprehensive its advantage, create a kind of novel filter plant, make it to be maintained fixed the once characteristics of a large amount of blowings of formula suction strainer groove, can change again it need artificial row unload filter and backwards mode of operation, replace and turn over groove with push-botton operation and arrange and unload filter also.This brand-new filter plant can improve liquid-solid separation greatly and filter the operating condition of operation, improves workshop condition, reduces labour intensity, improves filtrate and filter and quality and recovery rate, reduces the filter cloth loss, has huge economic benefit.

Now design of the present utility model, operation principle and technical characterictic are described by Fig. 1～of the present invention a kind of structure example shown in Figure 6.

The utility model is a kind of intermittently operated turning-over tank type vacuum filter that has high frame and can add seal cover, has frame 1, rotating turret 3, cylinder 5, motor 6, deceleration device 7, charging aperture 8, water inlet 9, filtrate draft tube 10, blow vent 11, hollow shaft 15, shaft coupling 12, bearing block 13 etc., its structure and technical characterictic are as follows:

1, the convertible suction strainer groove 2 of rectangle on the rotating turret 3 of being contained in that has a high frame, because its frame 26 is higher than the filter disc frame of the existing formula filter that turns over, thereby the requirement of can the disposable a large amount of blowings of adaptive response pot filtering.Rotating turret 3 is supported in (see figure 4) on the hollow shaft 15, and hollow shaft then is held on the frame 1 with 12 of two bearing blocks.The suction strainer notch upwards unloads when filtering also during filtration, and motor 6 drives the hollow shaft revolution by deceleration device 7, unloads filter and action thereby make convertible suction strainer groove finish the row of upset.

2, the suction strainer bottom land by both sides to intermediate, inclined, but be covered with the low clearance grid 29(Fig. 3 that has placing porous plate 35 above), there is an intercepting gutter 30(Fig. 5 who tilts in trench bottom central authorities), slurries are connected (Fig. 4) by the drain pipe 36 in the hollow shaft 15 of intercepting gutter feeding rotating turret 3 and with fairlead 27 and filtrate draft tube 10.Hollow shaft and the packing seal of filtrate draft tube compress with gland.The fairlead 27 that gland 37 has constitutes the rotary seal bodies with rotation stuffing box 28.The filtrate draft tube then is fixed on the frame 1.For ease of the mounting or dismounting maintenance, the drain pipe 36 that is placed in the hollow shaft 15 is made two sections with fairlead 27, sealed with sealing device.

3, can be provided with seal cover 4 on the rotary type suction strainer groove 2.Seal cover 4 is equipped with soft cavernous body sealing strip with cell body contact position suitable for reading, is furnished with charging aperture 8, water inlet 9 and blow vent 11 above the seal cover, connects with the outside of sebific duct and frame 3 respectively.Washings evenly are sprayed at filter full surface also by many uniform spray heads that are loaded on the seal cover inboard.The switching of seal cover is realized by two cylinders 5.Because the protective effect of seal cover, avoided that pernicious gas has improved workman's working condition to the pollution of environment in the reinforced and filter process of slip.

4, improved the installing and fixing method (seeing Fig. 3,5,6) of filter cloth.Also available metal silk cloth replacement of filter cloth in the utility model.A plurality of filter frames 25 are housed on porous plate 35, and whole filtering surface is divided into the polylith filter frame, and filter cloth 37 is laid on limit, filter frame 25 upper edge and clamps with Ω shape elasticity folder 16, and sealing is reliable, and mounting or dismounting are convenient, and the comparable existing suction strainer groove of filter cloth is saved over half.The filter frame that installs filter cloth can be fixed on the fillister head screw 19 on porous plate 35 limits with pressing plate 17 and eccentric handle 18, and also available plastic nut is fixed.Bottom surface on filter frame four limits is lined with soft sealing strip so that slip does not leak.

Because said structure characteristics of the present utility model, for filter, filter and washing, unload filter and etc. operation the possibility that adopts multiple method of operating is provided. This is that existing suction strainer groove (bucket) and revolving-leaf type filter are incomparable. Operating feature of the present utility model is:

1, adopt push-botton operation, row is also rapid, and filter cycle is short, and filter capacity is big.

2, have multiple filter operation method, as

(1) disposable a large amount of rapid loading while suction filtration;

(2) earlier reinforced after natural subsidence suction strainer again;

(3) can give adding to the slip of sad filter and help filtering layer to make in-depth filtration;

(4) do filter and filtration with returning the method for watering.

3, available several different methods is filtered and is washed, as:

(1) fountain washing method;

(2) immersion fluid column washing method;

(3) starch gas agitator treating method again;

(4) slurries body agitator treating method again;

(5) above-mentioned four kinds of washing methods operation also capable of being combined.

4, can be applicable to the unstable labile slip of material performance;

5,, accomplish the civilization operation to the salable reinforced filtration of poisonous material.

In sum, compare with the rotary vacuum filter that turns over existing vacuum suction filter groove, the utility model operating maintenance is convenient, reduces labour intensity, the speed production cycle, improve the quality of products, reduce the filter cloth loss, reduce production costs, improve workshop condition, help carrying out production strictly in line with rules and regulations, applicable to various liquid-solid separation and the filtration operation in the every profession and trade.
